Markdown files¶

Jupyter Book allows you to write your content directly in markdown files. If you’d like to include computational content with these markdown files, use the following directive:

```{execute}
print("Here is some code to execute")
```

When your book is build, the contents of any {execute} blocks will be executed with your default Jupyter kernel, and their outputs will be displayed in-line with the rest of your content.

For more information about executing computational content with Jupyter Book, see The MyST-NB documentation.
